4 Claims.

This invention relates to electric heaters and has for an object toprovide apparatus including an electric water heater, a hot waterradiator, a fan for disbursing heated air from the radiator throughoutthe space to be heated, and a sealed tank for separating steam vaporfrom the circulating water and permitting the vapor to escape into theatmosphere.

A further object is to provide a device of this character which will beformed of a few strong simple and durable parts, which will beinexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists ofcertain novel details of construction and combinations of partshereinafter fully described and claimed, it being understood thatvarious modifications may be resorted to within the scope of theappended claims without departing from the spirit or sacrificing any ofthe advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a front elevation of an electrically operated hot waterheating system constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view of the electric water heater.

Figure 3 is an enlarged cross sectional view taken on the line 3-3 ofFigure 2.

Figure 4 is a fragmentary longitudinal sectional view showing a modifiedform of electric water heater.

Figure 5 is a sectional view of a combined water expansion and feedwater supply tank.

Referring now to the drawing in which like characters of referencedesignate similar parts in the various views, l0 designates a hot waterradiator, the same comprising a casing II which houses upper and lowerwater receptacles l2 and I3 which are connected by a plurality of pipesM. A plug cap l5 closes an opening in the top of an upper waterreceptacle and through this opening air may be vented from the radiatorwhen the system is being filled.

An electric motor I6 is mounted in any preferred manner adjacent to thehot water radiator. The motor drives heated air from the hot waterradiator throughout the space to be heated such as a room or otherchamber.

An electric water heater I1 is provided for heating water or otherliquid with which the radiator is supplied. The heater comprises acasing 18 which houses upper and lower water headers I9 and 20 which areconnected by a plu- 1937, Serial No. 161,851

rality of pipes 2| preferably formed of glass and upon these pipeselectric heating coils 22 are sleeved as best shown in Figure 2.

However, the glass pipes may be dispensed with and metal pipes 24 may beused, as illustrated in it Figure 4, and these pipes are insulated asshown at 25. In this embodiment of the invention the heating coils 26are sleeved upon the pipes and are insulated.

The upper header IQ of the heater is in communication with the upperwater receptacle I2 of the radiator through a pipe 21. The lower waterreceptacle l3 of the radiator is in communication with a sealed tank 28through a pipe 29. The sealed tank is in communication with the lowerwater header of the heater through a pipe having a pet cock 3| by meansof which the heater may be drained when necessary. The sealed tank islocated above the water header 20 of the heater and is in horizontalalignment 20 with the lower water receptacle l3 of the radiator.

The sealed tank functions to separate steam vapor from the water flowingthrough the pipe 29 and pipe 30 into the bottom of the heater. The steamrises through a pipe 32 which enters the bottom of an expansion tank 33having a removable cover 34 which permits of filling the system withwater. A steam pipe 35 enters the expansion tank above the water leveltherein and overlies the hot water heater. The end of the pipe isequipped with a downwardly extending nozzle 36 which is in the path oftravel from the fan so that the steam will be blown out into the room tohumidify the room.

In some instances it is desirable that the expansion tank be equippedwith a feed water pipe 37, as best shown in Figure 5 for replenishingthe water in the system when necessary. The 0 pipe is equipped with afloat controlled valve 38 which automatically opens to restore the waterlevel in the tank 39.

While the apparatus above described may be used effectively as a heatingsystem the apparatus may also be used to separate soluble gas from aliquid or separate one liquid from another, such as the ammonia typerefrigerator where ammonia gas is separated from water by heat.

The electric water heater constructed as above described may beinstalled in the water system of a dwelling to heat water for thepurpose of supplying hot water from the water system.

From the above description it is thought that the construction andoperation of the invention will be fully understood without furtherexplanation.

What is claimed is:

1. Heating apparatus comprising an electric water heater, a hot waterradiator, flow and return pipes connecting the heater with the radiator,a fan adjacent the radiator for distributing heated air from theradiator throughout the space to be heated, a sealed tank connected inthe return pipe from the radiator to the heater adapted to separatesteam vapor from circulating Water and permit the steam to escape to theatmosphere, and a pipe connected to the sealed tank and opening into thedraft produced by the fan for humidifying the hot air delivered by thefan.

2. Heating apparatus comprising an electric water heater, a hot waterradiator, a pipe connecting the top of the heater with the top of theradiator, a fan directing its air blast upon the radiator, a sealed tankfor separating steam from return water, a pipe connecting the bottom ofthe radiator with said tank, said tank being disposed above the bottomof the heater and in horizontal alignment with the bottom of theradiator, a pipe connecting said tank with the bottom of the heater, acombined filling and steam pipe eX- tending from said tank, an expansiontank connected to the last named pipe, and a steam escape pipe connectedto the expansion tank above the water level of the expansion tank andopening into the draft produced by the fan.

3. Heating apparatus comprising an electric water heater, a hot waterradiator, flow and return pipes connecting the heater with the radiator,a fan adjacent the radiator for distributing heated air from theradiator throughout the space to be heated, a sealed tank in the returnpipe from the radiator to the heater adapted to separate steam vaporfrom circulating water, an expansion and filling tank connected to saidsealed tank and a pipe connected with said filling tank opening into thedraft produced from the fan for permitting steam to escape into thespace to be heated and be distributed by the fan for humidifying thespace to be heated.

4. Heating apparatus comprising an electric heater having upper andlower water headers connected by a plurality of pipes, heating coilssleeved on the pipes, a radiator having upper and lower waterreceptacles connected by a plurality of pipes, a pipe connecting the topheader of the heater with the top water receptacle of the radiator, apipe connecting the bottom water header 1 of the heater with the bottomwater receptacle of the radiator, a sealed tank in the last named pipedisposed above the bottom Water header of the heater and insubstantially horizontal alignment with the lower water receptacle ofthe radiator adapted to separate steam vapor from water, a pipeconnected to said tank and terminating adjacent to said radiator forpermitting steam to escape into the atmosphere, and a fan adjacent theradiator disposed to produce a draft upon the radiator and the pipe fordistributing heated air and steam vapor from the radiator and piperespectively to the space to be heated.
